Dr. Steven Shirey is a senior staff scientist of the Carnegie Institution for Science where he is a member of the four-person Geochemistry and Cosmochemistry Group of the Department of Terrestrial Magnetism. Independently and with his mentoring of PhD students, and postdoctoral fellows, Dr. Shirey researches geological processes pertaining to the igneous evolution of the solid Earth. The formation of diamonds has been an area of interest and research for Dr. Shirey for nearly two decades. He is noted for the study of mineral inclusions in diamonds which has been applied to global scale questions such as the age of diamond-forming events, the creation of the continents, the onset of plate tectonics, and the recycling of surface materials into the deeper parts of the mantle. Dr. Shirey is a fellow of the American Geophysical Union, the Geological Society of America, the Geochemical Society, and the Mineralogical Society of America where he served as its president. In addition to his work on lithospheric and superdeep diamonds, he has published widely on topics as diverse as arc volcanism, Archean crustal evolution, continental volcanism, meteorites and impacts, mantle heterogeneity, and isotope geochemistry method development. As of the end of 2018, his publications had earned a Google Scholar H-index of 60 with more than 13,000 citations.
